Granulation is an ancient jewelry technique whereby a surface is decorated with tiny spheres of metal, called granules, according to a design pattern. This technique is over 5000 years old and was found in royal tombs of Sumer from 1500 BC. This technique was used by Etruscans living in present day northern Italy, and the Greeks and then spread to India and Persia. The result is a rich yet delicate pattern creating texture and interest.
